On Saturday, mifua suddenly heard the sound of police cars whistling. Several police cars stopped on the roadside outside an ordinary apartment building. Soon after, a special phone call was made to the Chenghu detective office.

Gao Cheng takes Xiao AI to the apartment in a hurry. When he goes upstairs, he sees the calm police officer mu.

"What's the matter, officer?"

"Chenghu elder brother," Mu Mu saw Gao Cheng, and his face was a little better. "It was Mr. Sugimoto who was killed. He was a freelance writer..."

"Shansen?" Gao Cheng looks to the side and notices that Xiao Lin is also called to the scene. He looks like he is being questioned.

"That's right," murmured Mu Mu. "It's shansen, who originally planned to interview Conan. The time of his death was between 11:00 and 12:00 yesterday noon. The murder weapon was a tripod used by the camera. The murderer may be an acquaintance, or the writer is interviewing..."

"Did you find the suspect?" Conan's voice suddenly rang out in the back, and everyone on the scene was stunned at the same time.

Gao Cheng looked back and found that not only Conan, but also Bumei came with him: "Why are you here? Didn't I ask you to wait for me at the coffee shop? "

"Brother Chenghu is too eccentric. I'll take Xiaoai with me!"

"Yes, Mr. Xiaolin is in trouble. How can we ignore it?"

Guangyan complained: "besides, isn't brother Chenghu a member of our juvenile detective group? How can we leave us? "

"I'm not a member of the junior detective group," Gao Cheng said with black lines. "Now that I'm here, please be quiet. Don't interrupt..."

Mu Mu coughs lightly and interrupts Gao Cheng: "about the suspect, we have found four people who left messages at the time of the crime. The first one is Mr. Xiaolin..."

Gao Chengchao's worried teacher Xiao Lin nods and follows Mu Mu to the scene of the murder.

Outside the door, you can see a man in a vest collapsed on the wall, his head covered with blood, and his original handsome face looked a little ferocious.

Gao Cheng takes a look at the body and turns to the scene. He finds a tripod of the murder weapon stained with blood in a pile of books. As the man's body is carried away, the tripod is also installed by the identification personnel.

The answering machine was on the low table next to it, splashed with a lot of blood, and the message light was still flashing.

Gao Cheng looked closer and found that part of the blood on the message button had been wiped off.

"That's the problem," Mumu explained. "Someone pressed the message button after the crime to set the message status. If the victim regained consciousness after the prisoner escaped, it should be asking for help or calling the police, and the victim's fingers were not stained with blood..."

"That is to say, did the prisoner press it?" Gao Cheng opens his mouth.

"It should be right," Mu Mu nodded. "The important thing is that when the body was found, the door of the room was not locked, and the key was placed next to the phone, so it's not to delay the time when the body was found. It's likely that the prisoner left a message on the recorded phone and forged the alibi certificate, so we called teacher Xiaolin over..."

Gao Cheng put his hands in silence.

He had a general look. The prisoner looked very flustered. There was blood on the doorknob. He should have worn gloves and touched the bloodstain on the answering machine. When he ran away, he got on the doorknob again.

"We've recorded the messages separately," Mumu said with a player. "There are four messages in total..."

"Beep!"

"There are four messages... I'm Xiao Lin, a Xiao, the head teacher of class B in the first year of Didan primary school. I'm sorry, it seems that it's pollen allergy... I've asked for it for you. Detective Chenghu said that he had an interview with the daily TV station. I'm really sorry... Beep, 11:25 a.m..."

"Shansen? I'm Qinghua. I drank too much yesterday... Sorry, I'm not angry anymore... You always refuse to take me back to your home, so I think there are other women in your family... "

Gao Cheng listened carefully, but the background sound came from the recording.

"When it comes to pollen allergy, today's pollen is flying even worse. I don't know what countermeasures we have for pollen allergy..."

"Well," the second message just came to the end, "follow me when you hear the message... Beep, 11:26 a.m., Friday..."

"This is the" wholehearted TV "program broadcast at 11:00 noon on the daily TV station," Mu Mu interjected. "My wife Xiao Lu likes this program very much and often records it for me to watch it together... I think as long as I ask her, she will know the specific broadcast time of this period. It's really the time to leave a message."

Gao Cheng just saw Mu Mu's wife at her last wedding. She nodded and watched Mu Mu Mu play the third message.

"I'm Huiyuan... I'd like to meet you. I'm on my way to your house now... If I'm not at home, I'll come back another day..."

"The next stop is aosui..." the message suddenly rang out a station call, "aosui, please pay attention to your feet when you get off..."

"I'm really sorry about the car. Goodbye... 11:27 am, Friday..."

Gao Cheng looks up and looks at each other“ In the background is the radio in the tram, "Mu Mu explained." we checked that aosui station is at least 35 minutes away from here. Moreover, because the conductor who broadcast that day suffered from pollen allergy, "pay attention to the space under your feet" didn't finish, so the radio was not recorded in advance. "“ Is the alibi sufficient? "“ And the last message... "Beep, I'm Daoye from xingrongguan. I'd like to ask you how your report is going... Chief editor, what's the date today?" In the message, the other party seemed to be shouting to others. A middle-aged man immediately replied, "22, you must remember, Daoye!"“ Hold, sorry, that is to say there is a week to the deadline, please come on, shansen! Ah, I don't mind the report that revealed the inside story last time. Please pay more attention to it in the future... Editor in chief, are you really going to watch the night game today? "“ It doesn't matter. Today is the competition in Dongdu gymnasium. "“ Beep, 11:29 a.m., Friday... "It's from the company. Besides the person who called, there is an editor in chief." Mumu turned off the player. "We have contacted the editor in chief and said that it's not clear that the editors often go in and out, but the editor named Daoye should be in the editorial department at that time, because the mobile phone is not good, Daoye often asks him for the date... "After a pause, he looks out at the waiting teacher Xiaolin and continues:" that is to say, in addition to Xiaolin, the other three people have clear alibi. Although Xiaolin says that he has been staying in school, he has no sufficient alibi, so he has time... "" but, "Gao Cheng frowns, "Doesn't it mean that the prisoners set up messages to make alibi?"“ The problem is that it may be to disturb our police investigation... "Mr. Kobayashi has no motive, and even if Mr. Kobayashi is really a murderer, there is no need to do such a trick. If you don't leave a message, it won't cause suspicion." Gao Cheng looks at Chengzi Kobayashi who is talking with Bu Mei. It's a little sudden. The writer who had been looking for Mr. Xiaolin for the interview and report died suddenly. Mr. Xiaolin has become the biggest suspect. It's a bit of a coincidence to say that it's a coincidence. Maybe the prisoner knew about the victim's contact with Mr. Xiaolin from the very beginning, and knew quite well“ Officer, "Gao Cheng turned to Mu Mu," can I ask those people again? "“ Can pour is can...... "Mu Mu Leng Leng way," what place is wrong? "“ There are a few doubts. The second message doesn't matter even if you borrow the TV here. The last one, if you exclude that the chief editor is an accomplice, there is no way to make perjury... "Gao Cheng looks at the scene of the murder again“ So now the only one who really has an alibi is Huiyuan in the third message. "
